Digital Rear-View Mirror Touchscreens for Vehicle Function Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and cost of user interaction in vehicles equipped with digital rear-view mirrors are increased due to multiple interfaces and inaccessible authorization buttons, making it difficult for drivers to activate functions subject to authorization, especially while driving.
Innovation Solution
A method utilizing dual touch screens in digital rear-view mirrors to detect and transmit authorization requests for vehicle functions, allowing drivers and passengers to easily accept or refuse these requests through an interactive notification system, reducing the need for direct button access and simplifying the authorization process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional buttons and separate authorization interfaces are used, then functions subject to authorization can be activated, but the device complexity and manufacturing cost increase due to multiple interfaces and components
Solution Approach 1:
The patent merges the authorization interface with the digital rear-view mirror display system. The touch screen of the digital mirror serves dual purposes: displaying rear-view images and handling authorization requests for vehicle functions. This consolidation eliminates the need for separate authorization buttons or interfaces, reducing component count and complexity while maintaining full authorization functionality.
Solution Approach 2:
The digital rear-view mirror touch screen is designed to perform multiple functions: it displays the rear-view camera feed, provides climate control settings, and handles authorization requests for various vehicle functions. This multi-functional design allows a single interface to replace multiple specialized interfaces, reducing overall system complexity.
2Adaptability or versatility
If authorization buttons are placed in traditional locations, then functions can be authorized, but the ease of operation deteriorates because drivers cannot easily access buttons while driving
Solution Approach 1:
The digital rear-view mirror touch screen acts as an intermediary interface between the driver and the authorization system. Instead of requiring direct interaction with physical buttons located in hard-to-reach areas, the driver can interact with the authorization requests displayed on the mirror's touch screen, which is positioned in the driver's natural field of view and easily accessible.
Solution Approach 2:
The patent transitions from a three-dimensional physical button interface to a two-dimensional touch screen interface displayed on the mirror surface. This dimensional change allows authorization requests to be presented visually in the driver's line of sight, eliminating the need for physical access to buttons located on door panels or dashboard edges.
3Adaptability or versatility
If multiple separate interfaces are provided for mirror functions and vehicle functions, then all functions can be controlled, but the ease of operation worsens due to user confusion from multiplicity of interfaces
Solution Approach 1:
The patent combines the control interface for digital mirror functions and vehicle function authorizations into a single unified touch screen interface. The same display shows both mirror adjustment options and authorization requests, allowing users to interact with all functions through one consistent interface rather than switching between multiple separate controls.

AI summary
A method and a device are disclosed for activating a function subject to authorization in a vehicle comprising a system of digital rear-view mirrors with at least first and second touch screens, arranged on the driver's and passenger's side, respectively. The vehicle comprises members suitable for providing at least one function subject to authorization. The method comprises detection, by one of the members, of an action by a person that requires the activation of a function subject to authorization; —transmission, from the member to the system of digital rear-view mirrors, of information relating to the detection; —receipt, from the system of digital rear-view mirrors, of the information relating to the detection originating from the member, —display, on one of the touch screens, of a notification comprising the function subject to authorization, and; an interaction zone suitable for receiving either an agreement or a refusal from the driver and/or the front passenger.
